[Leica] M8 trials and tribulations?

[grduprey at mchsi.com (grduprey@mchsi.com)]

Hoppy,

the cell on the m8 is for flash exposure not aperture calculation.  the 
nikon aperture window works because the aperture ring is right under the 
pentaprism, where the aperture ring on m lenses is way out on the front of 
the lens and the window would not work here.  on the d200 if you have a ais 
lens you will have aperture info, if you program the menue for it.  for 
other lenses it can only tell you how far stopped down you are from wide 
open, not the actual aperture is.
